Re: Any cure for a rubbing speaker cone?
Its usually not too difficult to separate the coil sleeve from the cone, having unsoldered the pigtails first.
Then you can clean out the magnet and pole gap thoroughly, scraping and blowing the rust out, stick paper to finish off.
Centre the coil with 3 paper slips and reglue to the cone. UHU works well.
Done a few, tricky but possible with care.
